Koi... Mil Gaya

Jeered at by much younger school friends for not knowing anything about computers, the alien Jadoo teaches him what he needs to know. He comes back triumphant, telling the other kids that his deceased dad taught him computers, after all.

Andaz

David Dhawan's 1994 film is the kind of thing that would have Slumdog Millionaire's Anil Kapoor scurrying for cover.

In one of the most embarrassing 1990s films, he plays a schoolteacher married to Juhi Chawla, fighting off a crush from schoolgirl Karisma Kapoor. The height of the inanity? Shakti Kapoor playing her classmate.

Khiladi

Back when Abbas-Mastan were in top form, they made this fun thriller that started off innocuously enough in a college.

Akshay Kumar leads a group of pranksters to lace the teachers' drinks with 'winking powder,' and, correctly anticipating the chaos to follow, prepares for appeasal by showering the angry teachers with roses kept atop the ceiling fan.

Someone walks in and Kumar switches the fan on, but it isn't a teacher, it's new student Ayesha Julka. Love, naturally, is born.

Shree 420

In this utterly charming Raj Kapoor film -- the man wrote, produced, directed and played the main lead, in his usual everyman way -- Nargis played a teacher, and who can forget the wonderfully written educational track Eechak Daana Beechak Dana, the Shankar-Jaikishen song immortalised by Lata Mangeshkar and Mukesh.
